counters for adding purposes; and'the object claims.

of the invention is to produce such 'a key that will insure a positiveoperation of the counter when actuated by any suitable means forimparting movement thereto. A portion of a registeringmachine embodyingmy said invention, wherein the advantages sought are attainecLwill firstbe more particularly described in the annexed specification and thenovel features thereof then pointed out in the Referring to theaccompanying drawings, which are made a part hereof, and on whichsimilar numerals of reference indicate similar parts, Figure 1 is afragmentary detail in vertical section of a registering-machine in whicha plurality of keys are shown in operating position. In this view a partof the keys is shown in side elevation and a part in section. Fig. 2 isa fragmentary detail view in horizontal section of theregistering-machine and shows in top plan view the mechanism foroperating the key to actuate the counter. Fig. 3 is a fragmentary detailView as seen when looking in the direction indicated by the arrows onthe dotted line 3 8 in Fig. 2. Fig. 4 is a fragmentary detail view asseen when looking in the direction indicated by the arrows'on the dottedlines 4 4 in Fig. 3.-

Fig. 5 is an under side plan view of the construction shown in Fig. 3.Fig. 6 is a pers ective view of one of the counters and s ows the stopbar for stopping the counters at a given point when the latter arereset.

In the drawings, 1 constitutes the inner frame, which may be of anysuitable shape to conform to the style of a machine desired and supportsthe keys and counters.

Examining Figs. 1 and 2 of the drawings, it will be seen that I canarrange my keys and chine.

counters in series, either in a vertical .or

horizontal direction, or both. As the several keys and theiraccompanying counters shown throughout the several views of the drawingare all similarly constructed, adescription of i one is deemedsufficient for all.

The front portion of the key 5, hereinafter known as the primary member,is provided with a knob 6, by which sufiicient purchase can be obtainedfor manipulating the key.

The primary member 5 of the key passes through the apertures 7 and 8 inthe walls 9 and 10, secured to the frame of the registering-machine toform a guide for said member. The member 5 is also provided with a pin12 for re ulating the backward movement there of. The rear end of theprimary member 5 is provided with a slot 14, which slot receives atongue '15, formed on the rear portion of the key hereinafter known asthe secondary member 16. The primary member 5 and secondary member 1.6are pivotally secured together by means of the transverse pin 17.

.The secondary member of the key is provided with an elongated slot 19to receive a cam for returning the key to normal position, which will behereinafter described. The extreme rear end of the key is greatlyreduced in width, so as to provide the narrow extending finger 20, whichen ages a ratchet-wheel formed integrally wit the units-disk of thecounter, so that the latter is operated when the key' is returned tonormal position.

Situated beneath the secondary member 16 of the key is the cam-shaft 25,which is mounted at right angles to the key and is supported in theframe 1 of the registering-ma- The cam-shaft 25 is provided with asegmental disk 26, which is adjustably secured thereto and engages withthe elongated 'slot 19 in the secondary member 16 of the key. Thesegmental disk 26 is provided with a cam-slot 30, and by means of a pin31,

that passes transversely through said .slot and the secondary member 16of the key, the key and segmental disk are linked together.

When the segmental disk 26 is standing in normal position, which isindicated by the full'lines in Fig. 1 of the drawings, the key' may bepulled forward and subsequently returned to normal position, if desired,as the elongated slot 19 m the secondary member ofth'c key and thecam-slot in. the segmental disk26 permit this movement. WVhena key,however, ispulled -forward,in which the cameslot ,30 permits thesecondary member 16' to'descend, as shown in'the uppermost key in'Fi'g.lot the drawings, and the move- '-.ment isthen reversed, the cam-slot 30in the segmental disk 26 is cuton a radius that per mlts the key toreturn to normal position without permitting. said secondary .member160i the key :to contact the ratchet-wheel and thus operate andchangethe total on the counter, This feature is of'the highest im-=satisfaction,' it' may be returned to normal,

and with which same movement the counter is op'erated,'b means ofithe"segmental disk 26 and cam-s ot'30. The distance :and the arc throughwhich the segmental disk 26 passes when returning. the keyfrom its open-'ated-to normal position is shown icy-means of the'full and dotted linesin Fig. 1 of the-draw lngs. The mechanism for operatin the segmentaldisk 26 will now be describe Examining Figs. 2 and 3 of the drawings, it

will be 'seenthat thergistering-machine is rovidediwith an exterior orouter frame 40 or housing the inner frame. Secured m'a' suitable'mannerto the outer'frame 40, at one" end of, the machine, is the boX 41, thatforms a bearingfor a revoluble drum 42 by means of a s in'dle 43and nut45. ,The' drum '42 and ot er mechanism de endent-thereon are operated bymeans of on said drum.

A bar 50, provided with an integrally formedear 51,- which is providedWith'a cam- I direction indicated by the arrow above said .pinion inFig.- 4; This-movement of the pinslot'52, is. slidably mounted on theunder side of the inner frame. 1 and is pivotally connectedtothe drum 42bymeans of the pitman55. A'rack-barSS 1s s'lidably mounted on the-side.of the inner frame-1 and transverselywith the sliding'bar 50.; Thelower end of the rack -bar- 58 isprovided with afslot '59 .(see Fig. 4)and carries thefrictionqoller 60,.th'at engages with the ca'mslot'52 inthe",

' ear-51 on the: sliding bar 50. i The sliding bar 5Q also provided witha slot 63, as shown in Fig. 5, inorder topermit one ofthe-extending-side's of'the rack-bar 58, formed by theslot 63, topass;"By means of this construce -tion it will be seen that when the drum 42is opera-ted theslidin'g bar-'50, car 51 and the rack-bar 58 through thelatters connection with sliding 'bar'50, are operated.- The di- .-6o

rection takengby the parts 1 s-only conjecture unless a certaindirection taken is described inithe initial movement, .andthis will behereinafterset forth Attention has previously been directed to a 'andle47., mounted cam-s sagas 5' the cam-shaft 25, which carries thesegmenital disk .26 and which is supported in the inner frame 1 of themachine.

Throughout the several views of'the drawings it willbe noted that wheresaid shaft 25 passes through the side of the frame-1, havin the rack-bar58 slidably secured thereto, said shaft 25is provided with a pinion 65,that is rigidly secured.

thereto. The pinion 65 meshes with the rack-bar 58,and obviously whensaid bar is.

actuated the shaft 25 and-segmental disk 26 are rocked. I

Accompanying the key and situated in the rear and in alinementtherewithis the counter 7 0', which is composed OfttSGIlQS of disks Inorder to clearly understand the initial movements of the parts of theregistering? machine and the norm'alposition of the keys 7 and cams, anoutline of the {mode of operation mounted in the drum 42, is moved. fromits normal position shown-by the full linesinto the direction indicatedby the arrowin Fig. 2.

[seems desirable, which is as follows: To op-- crate the registeringdevice, the handle 47,

This movement of the drum 42 through. the pitman' 55 moves. the sliding.bar 5O away. 1

from said drum. This movement of the slid-- ing bar causes the rack-bar58 to descend The ownward movement of the rack-bar with, to be movedfromright toleft, or in the 'linesin'the uppermost'key. (Shown inFlg. 1.)

Thismovement of the segmental disk 26 does "not affect the key, thelatter remaining normal and in; contact with theratchet-wheel on thecounter. After this movement of the segmental disk-the key may be pulledoutby gmeans of the cam slot 30, the latter permitthrou h its connectionwith'the cam-slot 52.

'58-.ca'uses the pinion 65, that meshes thereting the secondary member16 of the key to descend, asshown, in the uppermost key in Fig.1. -Whenthat key has been pulled-out that will subsequently actuate the counterin order to re ister the desired amount, the. return of sai key isefiected by reversingthe movement of the handle 47, whichmoves-thesliding bar 50 toward'itand by means of the ot-52 the rack-bar 58ismoved upward. This reverse movementof the bar causes the pinion to rockthe cam-shaft 25 from the position indicated by full lines to theposition lndicated by dotted lines in Fig. 1, and during which movementthe segmental disk raises the secondary member 16 of the key andsimultaneously with the. upward and backward movement thereof the key ispassed through an are by means-of the camslot 30 in the segmental disk26, that permits it to engage the succeeding tooth in the ratchet wheel,and thus actuate the counter.- The arts now having been restored to normal, rther registration requires a repetition ofthe above-describedmovements.
